Ok this is doing my head now I had the engine light on so I scanned the car and it says before cat lambda dodgy so changed it out and cleared the codes and within 5 miles of driving it the engine light came on again so plugged in again same problem :S so lucky for me have another clio with the same lambda that is 100% fine and within 5 miles light on again same problem :quiet: so wtf can it be ? Even stole the plugs out of my other clio but these are all fine. Any help would be great guys as its getting silly now
